If you’re totally stumped, you can tell the computer to show you the answer to a particular question. Monohybrid Cross: In humans, brown eyes (B) are dominant over blue (b)*. Dragon Delivery Lesson Snapshot 1. Engage: Students will watch a video or look at a picture and identify all of the similarities and differences of dragons. 2. The Blood Typing Game - about blood groups, blood typing and blood transfusions What happens if you get a blood transfusion with the wrong blood type? Even though a patient's own blood type is the first choice for blood transfusions, it's not always available at the blood bank. Try to save some patients' lives and learn about human blood types!

Kentucky Blues The story of an Appalachian malady, an inquisitive doctor, and a paradoxical cure. by Cathy Trost ©Science 82, November, 1982 Six generations after a French orphan named Martin Fugate settled on the banks of eastern 's Troublesome Creek with his redheaded American bride, his great-great-great great grandson was born in a modern hospital not far from where the creek still runs. Double Blasted In early August of 1945, Tsutomu Yamaguchi had a run of the worst luck imaginable. A double blast of radiation left his future, and the future of his descendants, in doubt. In this short: an utterly amazing survival story that spans ... well, 4 billion years when you get down to it.
What Is Hemophilia? Hemophilia (heem-o-FILL-ee-ah) is a rare bleeding disorder in which the blood doesn't clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed inside your body (internally), especially in your knees, ankles, and elbows. This bleeding can damage your organs and tissues and may be life threatening. Overview Hemophilia usually is inherited. Acquired traits can be inherited via small RNAs Columbia University Medical Center (CUMC) researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution was eclipsed by Darwin's, may not have been entirely wrong. The study is slated to appear in the Dec. 9 issue of Cell.
Blackett Family Pedigree Create a Blackett Family Pedigree Blackett Family Members The Blackett Family DNA Activity is largely a genetic study of the inheritance of alleles in an extended family. Bob Blackett has tested DNA samples from himself and 13 other relatives. The first task of a human geneticist is the creation of a family tree, or pedigree to help with the interpretation of genotypes. From the following relationships, construct a pedigree for the Bob and his relatives.
Haemophilia Haemophilia (also spelled hemophilia) is a group of hereditary genetic disorders that impairs the body's ability to control blood clotting, which is used to stop bleeding when a blood vessel is broken. Haemophilia A (clotting factor VIII deficiency) is the most common form of the disorder, present in about 1 in 5,000–10,000 male births. Haemophilia B (factor IX deficiency) occurs in around 1 in about 20,000–34,000 male births. Like other recessive sex-linked, X chromosome disorders, haemophilia is more likely to occur in males than females. This is because females have two X chromosomes while males have only one, so the defective gene is guaranteed to manifest in any male who carries it. Because females have two X chromosomes and haemophilia is rare, the chance of a female having two defective copies of the gene is very remote, so females are almost exclusively asymptomatic carriers of the disorder.
Color Blind Chart Pattern baldness in men is a sex-influenced trait. It is not an X-linked trait like color blindness and hemophilia. Baldness is an autosomal trait and is apparently influenced by sex hormones after people reach 30 years of age or older. This condition is inherited as a simple Mendelian trait, although the biochemical mechanism is complex. There are other causes for baldness not related to simple Mendelian genetics, such as illness, severe stress, and pulling one's hair out by the roots.
Concord Consortium Research Overview Geniverse research is being led by our research partner, BSCS, with assistance from our evaluator partner, TERC. Our research study is examining how the Geniverse materials affect students’ genetics content knowledge and abilities to engage in scientific argumentation. In addition to pre- and post-tests for content knowledge, we will measure both student motivation and the degree of fidelity of implementation of Geniverse. Student demographic variables (race/ethnicity and gender) are being collected to examine if the Geniverse materials provide equitable opportunities for students to learn. We are also examining the affects of a range of teacher characteristics (years using Geniverse, familiarity with instructional technologies, genetics background and experience with scientific argumentation pedagogies) on student outcomes.
National Hemophilia Foundation Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is a genetic disorder caused by missing or defective factor VIII, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a change in a gene. According to the US Centers for Disease Control and Prevention, hemophilia occurs in approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia in the US. All races and ethnic groups are affected. Hemophilia A is four times as common as hemophilia B while more than half of patients with hemophilia A have the severe form of hemophilia.
Quick Trait Calculator - Genetic Heredity Calculator Note These calculators use simplified models to calculate traits and their certainty is far from 100% due to the fact that human genetics is far more complex than a simple mendelian dominant/recessive model. Personal Report and Heredity Report give better results, providing that you had your genome sequenced by a commercial personal genomics companies like 23andMe, deCODEMe or Family Tree DNA.
